EDVARD F. VHITE, OF QUINOY, MASSACHUSETTS, ASSIGNOR OF ONE-HALF TOJ. E.TIBBETTS, OF BROOKTON, MASSACHUSETTS.

.ROTARY RAN D.

SPECIFICATION forming part of Letters Patent No. 559,508, dated May 5,1896.

Application filed February 12, 1896. Serial No. 579,031. (No model.)

To @ZZ whom t may con/cern:

Be -it known that I, EDWARD F. WHITE, of Quincy, in the county ofNorfolk and State of Massachusetts, have invented a new and usefulImprovement in Rotary Rands, which will, in connection with theaccompanying drawings, be hereinafter fully described, and specificallydefined in the appended claims.

In said drawings, Figure l is a side elevation of my improved rotaryrand, with its shaft, the box and the iixed and slowly rotatin g collar.Fig. 2 is a central longitudinal section through all the parts. exceptthe shaft, and that is shown in section at and near the front end. Fig.3 is a detached front elevation of my improved rotary rand, and Fig. 4is a side elevation of the same.

The object of this invention is to quickly, and by a power-driven tool,cut away around the heel portion of a boot or shoe the portion of theouter sole adjacent to the upper, a duty heretofore performed by hand;and the invention consists in a peculiarly-formed randing-tool arrangedin a protecting-shield that rotates only as the movement of the heeltends to move it, While the rotary rand revolves at high velocity andits nely-cut teeth remove the desired amount of the sole, the teeth ofthe rand being so formed that they cut only to the required depth inpassing along the sole, as will be next herein described and thenclaimed.

Referring again to said drawings, A represents the shaft on which therotary rand is secured, and B is a box in which one end of the shaft ismounted, said box being preferably formed with a smaller portion c, thatis duly secured in a suitable bearing, and b, that is arranged outsidesaid bearing. A collar c is threaded upon a reducedportion n of part b,so as to be adjusted outward and inward, and it is secured at thedesired point by a screw d, that bears against part n when set againstthe same. An outer trumpetshaped shield e is mounted loosely on saidpart n, and it is formed with a reduced portion p, that extends beneaththe imvardly-reduced portion of collar c, and it is secured in place bythe screws f threaded in parte and that travel freely in acircumferential groove in part p of said collar e. The rotary rand isshown at g, and it is secured upon the outer end of shaft A by screw Z,that bears upon awasher fm. Said rand is formed with a central openingh, that ts closely upon a reduced part of shaft A. It is also formedwith a slightlyreduced central portion t, and the portion outside ofsaid part i is divided into the smooth portions j and the toothedportions lo. Said teeth are what are known as ratchetshaped teeth, andthey rise above the adjacent surface j enough to constitute the extentof a cut upon the sole. Said rand is upon the back or inner yfacereduced toward the outer edge, so that', as shown, it will be entirelyWithin shield e, except the slight extent to which its teeth extendbeyond surface j', as already explained.

In operation box B and collar e do not revolve, collar @will move to thelimited extent due to the movement of the shoe, but the rand and shafthave a high velocity when in use.

The especial use of "this rand is to cut away the sole around the heel,as shown in Fig. 2, before trimming the outer edge of the same.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, `isl. The combination of a rotary rand dulymounted and secured upon shaft A, the trumpet-shaped inclosing shield e,arranged to move with the heel of the shoe, and collar c secured uponbox B and loosely connected with shield e, for the purposes specified.

2. A rotary rand g formed with a central recess t', the ratchet-teeth kand the smooth interspaced parts j, sunk slightly below the cutting edgeof said teeth, substantially as specified.`
